DRAFT-RIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed November 3, 1905. Serial No. 285,755;

To all whom it may concern:

Be it known that I, FRANK L. ENGLE- HARDT, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a specification.

My invention relates to improvements in draft-rigging for railway-cars.

In the draft-rigging heretofore in use difliculty is sometimes experienced from the draw-bar strap or yoke buckling or bending under severe buffing strains.

The object of my invention is to provide a railway draft-rigging of a simple, eflioient, and durable construction in which the drawbar strap or yoke will be effectually protected against liability to buckle or bend under buffing strains or blows.

My invention consists in the means I employ to practically accomplish this object or that is to say, it consists in connection with the draw-bar, draw-bar strap or yoke, tandem-arranged springs and followers, and side plates or stop-castings, of a stationary guide-block secured to and extending between the side plates or stop-castings, and provided with guide-grooves having overhanging guide-flanges and guide-blocks secured to the upper and lower members of the draw-bar strap and having guide-flanges fitting in the guide-grooves on the stationary guide-block which is secured to the side plates or stop-castings My invention also consists in the novel construction, of parts and devices and in the novel combinations ofparts and devices herein shown and described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partly in longitudinal vertical section, of a draft-rigging embodying my invention. Fig. 2 is a plan view partly in horizontal section. Figs. 3 and 4 are vertical cross-sections on lines 3 3 and 4 4 of Fig. 2, respectively. Fig. 5 is a detail perspective view of the stationary guide-block which fits between and is secured to the side plates or stop-castings, and Fig. 6 is a perspective view of one of the longitudinally-movable guide-blocks which is secured to and moves with the draw-bar strap or yoke.

In the drawings, A represents the center sills, A the draft-timbers, A the cross-sill, A the buffer-block, and A the carry-iron, of a car. B is the coupler, B the draw-bar, and B the draw-bar strap or yoke, secured to the draw-bar by the customary bolts or rivets b. C C are tandem-arranged springs, D D the side plates or stop-castings, and E the followers, the stop-castings having stops (1, d, d", and d for the followers to abut against, and also stops or shoulders d, d (1, and d to limit the movement of the followers and the compression of the springs. All these parts are or may be of any suitable or well-known construction familiar to those skilled in the art.

F is a stationary guide-block fitting and extending between the side plates or stopcastings D between the two intermediate followers and rigidly and firmly secured to the side plates or stop-castings by a bolt f, which preferably also extends through the drafttimbers. The stationary guide-block F is further anchored to the side plates or stopcastings by tongues or projections f, which fit in vertical grooves d in the side castings D at the middle portion thereof. The stationary guide-block F is provided with upper and lower channels f and guide-grooves f each having an inwardly-projecting flange f 3 to embrace the corresponding cooperating flanges g of the movable or reciprocating guide-blocks G, which are secured to and reciprocate with the draw-bar strap B The guide-blocks G are secured one to the upper member of the strap B and the other to the lower member of said strap B on the inside of the strap by rivets g. As the draw-bar reciprocates the guide-blocks G, with their tongues or flanges g snugly fitting in the guide-grooves f effectually prevent all liability or danger of the draw-bar strap buckling or bending. By thus providing the side plates or stop-castings of thedraft-rigging with guides or flanges which embrace and confine the upper and lower members of the drawbar strap or guide devices rigidly secured thereto I am enabled to effectually prevent all danger of the draw-bar strap buckling or bending, while at the same time permittmg it to properly reciprocate in respect to the side plates or stop-castings, and at the same time I do not materially increase the cost of the draft-rigging or its dimen- 810113.

1. In a draftrigging, the combination with the draw-bar strap or yoke, tandemarranged springs and followers, of stop-castings, guide-blocks secured to the upper and lower members of the draw-bar strap or yoke and a stationary guide-block rigidly secured to and extending between the side plates or stop-castings and having guide-flanges embracing the guide-blocks on said strap or yoke and supporting and guiding said strap or yoke, and a bolt extending through said guide-block and stop-castings, substantially as specified.

2. In a draft-rigging, the combination with the draw-bar strap or yoke having guide devices secured thereto, of a stationary guide-block having guide devices embracing the guide devices on the draw-bar strap to prevent the strap from bending or buckling under buffing strains or blows, and stopcastings between which said guide-block extends and to which it is rigidly secured, and a bolt extending through said guide-block and stop-castings, substantially as specified.

3. In a draft-rigging, the combination with the draw-bar strap or yoke having guide-blocks secured thereto furnished with guide-flanges, of a stationary guide-block having guide-grooves in which the guideflanges of the guide-blocks on the draw-bar strap fit and reciprocate, and stop-castings between which said guide-block extends and to which it is rigidly secured, and a bolt extending through said guide-block and stopcastings, substantially as specified.

4. In a draft-rigging, the combination with a stationary guide-block F, having guide-grooves f, of a draw-bar strap having guide-blocks G furnished with guide-flanges g fitting and reciprocating in said guidegrooves of said stationary guide-block F, stop-castings between which said guideblock extends and to which it is rigidly secured, and a bolt extending through said guide-block and stop-castings, substantially as specified.

5. In a draft-rigging, the combination with the side plates or stop-castings having upright grooves d of a stationary guide block F having tongues or projections f fitting in said grooves (1 a bolt f extending through said block F and the side plates or stop-castings, and a draw-bar strap provided with guide-blocks G having tongues or flanges g fitting in the guide-grooves f of said stationary guide-block F, substantially as specified.

6. In a draft-rigging, the combination with a stationary guide-block F having channels in its upper and lower faces, and horizontally-extending guide-groovesf and inwardly-projecting flanges f and a drawbar strap having guide-blocks G furnished with guide tongues or flanges g, substantially as specified.
